Viral nation

A virus has killed 95 percent of the world's population. In the United States, the survivors live in fifty walled cities, and an organization known as the Company runs all of them. It ended the plague with a vaccine brought back from the future.

The Company now rations food and supplies by lottery and requires daily doses of virus suppressant. It also watches future timelines so that crimes can be stopped before anyone commits them.

Clover Donovan is sixteen, autistic and brilliant. She has long wanted to attend the Waverly-Stead Academy, and her brother West, who looks after her, has worked hard to get her there. She will not give up her service dog, though, and the school turns her away.

The Company drafts her into the Time Mariners instead, a team of operatives who travel through time to collect news of the future. One of her missions shows her that West's life is in danger.

To alter what is coming, the Donovans must stand against the Company, and as they learn more of its secrets, its claim to be a benevolent ruler begins to look false. Clover joins a group of misfits and outsiders who are drawn toward open revolt.
